GTP cyclohydrolase I.
based on mapping to UniProt Q8Y5X1
GTP + H(2)O = formate + 2-amino-4-hydroxy-6-(erythro-1,2,3- trihydroxypropyl)-dihydropteridine triphosphate.
-!- The reaction involves hydrolysis of two C-N bonds and isomerization of the pentose unit; the recyclization may be non-enzymic. -!- Involved in the de novo synthesis of tetrahydrobiopterin from GTP, with the other enzymes involved being EC 1.1.1.153 and EC 4.2.3.12.
